glutget(3)
NAME
glutGet - retrieves simple GLUT state represented by inte
gers.
SYNTAX
int glutGet(GLenum state);
ARGUMENTS
state Name of state to retrieve.
- GLUT_WINDOW_X
- X location in pixels (relative to the screen ori
gin) of the current window. - GLUT_WINDOW_Y
- Y location in pixels (relative to the screen ori
gin) of the current window. - GLUT_WINDOW_WIDTH
- Width in pixels of the current window.
- GLUT_WINDOW_HEIGHT
- Height in pixels of the current window.
- GLUT_WINDOW_BUFFER_SIZE
- Total number of bits for current layer of current
window's color buffer. For an RGBA window, this is
the sum of GLUT_WINDOW_RED_SIZE, GLUT_WIN
DOW_GREEN_SIZE, GLUT_WINDOW_BLUE_SIZE, and
GLUT_WINDOW_ALPHA_SIZE. For color index windows,
this is the size of the color indexes. - GLUT_WINDOW_STENCIL_SIZE
- Number of bits in the current layer of current
window's stencil buffer. - GLUT_WINDOW_DEPTH_SIZE
- Number of bits in the current layer of current
window's depth buffer. - GLUT_WINDOW_RED_SIZE
- Number of bits of red stored the current layer of
current window's color buffer. Zero if the cur
rent layer of the current window is color index. - GLUT_WINDOW_GREEN_SIZE
- Number of bits of green stored the current layer
of current window's color buffer. Zero if the
current layer of the current window is color
index. - GLUT_WINDOW_BLUE_SIZE
- Number of bits of blue stored the current layer of
current window's color buffer. Zero if the cur
rent layer of the current window is color index. - GLUT_WINDOW_ALPHA_SIZE
- Number of bits of alpha stored the current layer
of current window's color buffer. Zero if the
current layer of the current window is color
index. - GLUT_WINDOW_ACCUM_RED_SIZE
- Number of bits of red stored in the current layer
of current window's accumulation buffer. Zero if
the current layer of the current window is color
index. - GLUT_WINDOW_ACCUM_GREEN_SIZE
- Number of bits of green stored in the current
layer of current window's accumulation buffer.
Zero if the current layer of the current window is
color index. - GLUT_WINDOW_ACCUM_BLUE_SIZE
- Number of bits of blue stored in the current layer
of current window's accumulation buffer. Zero if
the current layer of the current window is color
index. - GLUT_WINDOW_ACCUM_ALPHA_SIZE
- Number of bits of alpha stored in the current
layer of current window's accumulation buffer.
Zero if the current layer of the current window is
color index. - GLUT_WINDOW_DOUBLEBUFFER
- One if the current layer of the current window is
double buffered, zero otherwise. - GLUT_WINDOW_RGBA
- One if the current layer of the current window is
RGBA mode, zero otherwise (i.e., color index). - GLUT_WINDOW_PARENT
- The window number of the current window's parent;
zero if the window is a top-level window. - GLUT_WINDOW_NUM_CHILDREN
- The number of subwindows the current window has
(not counting children of children). - GLUT_WINDOW_COLORMAP_SIZE
- Size of current layer of current window's color
index colormap; zero for RGBA color model layers. - GLUT_WINDOW_NUM_SAMPLES
- Number of samples for multisampling for the cur
rent layer of the current window. - GLUT_WINDOW_STEREO
- One if the current layer of the current window is
stereo, zero otherwise. - GLUT_WINDOW_CURSOR
- Current cursor for the current window.
- GLUT_SCREEN_WIDTH
- Width of the screen in pixels. Zero indicates the
width is unknown or not available. - GLUT_SCREEN_HEIGHT
- Height of the screen in pixels. Zero indicates the
height is unknown or not available. - GLUT_SCREEN_WIDTH_MM
- Width of the screen in millimeters. Zero indicates
the width is unknown or not available. - GLUT_SCREEN_HEIGHT_MM
- Height of the screen in millimeters. Zero indi
cates the height is unknown or not available. - GLUT_MENU_NUM_ITEMS
- Number of menu items in the current menu.
- GLUT_DISPLAY_MODE_POSSIBLE
- Whether the current display mode is supported or
not. - GLUT_INIT_DISPLAY_MODE
- The initial display mode bit mask.
- GLUT_INIT_WINDOW_X
- The X value of the initial window position.
- GLUT_INIT_WINDOW_Y
- The Y value of the initial window position.
- GLUT_INIT_WINDOW_WIDTH
- The width value of the initial window size.
- GLUT_INIT_WINDOW_HEIGHT
- The height value of the initial window size.
- GLUT_ELAPSED_TIME
- Number of milliseconds since glutInit called (or
first call to glutGet(GLUT_ELAPSED_TIME)). - GLUT_WINDOW_FORMAT_ID
- The window system dependent format ID for the cur
rent layer of the current window. On X11 GLUT
implementations, this is the X visual ID. On
Win32 GLUT implementations, this is the Win32
Pixel Format Descriptor number. This value is
returned for debugging, benchmarking, and testing
ease.
DESCRIPTION
glutGet retrieves simple GLUT state represented by inte
gers. The state parameter determines what type of state to
return. Where appropriate, window capability state is
returned for the layer in use. GLUT state names beginning
with GLUT_WINDOW_ return state for the current window.
GLUT state names beginning with GLUT_MENU_ return state
for the current menu. Other GLUT state names return global
state. Requesting state for an invalid GLUT state name
returns negative one.
